One option:
D = readtable('diabetes.csv');
VN = D.Properties.VariableNames;
Dmtx = table2array(D);
figure
semilogy((1:size(Dmtx,1)), Dmtx, '.')
grid
xlabel('Row #')
legend(VN)
That will plot all the variables as a function only of the row in ‘Dmtx’.
Choose what to plot (and what to use as independent or dependent variables) as necessary to depict the required trends. Choose those either as columns of ‘Dmtx’ or as variables in ‘D’.
